Abstract
A soft sealing flat valve contains a valve body, a shutter, a valve stem, a valve cover and a handwheel. A sealing plain cushion is arranged between the valve cover and the valve body; the valve cover is connected with the valve body by a washer and a bolt. The utility model is characterized in that: a seal element covers the surface of both sides or the whole surface of the shutter; a joint of the inner wall of the valve cover and the valve stem is provided with a shaft sleeve, a sealing ring, an O-ring, a spacing ring and a clasp; the bottom of the valve body is provided with a sewage outfall and a plug; the shaft sleeve covers the joint of the valve stem and the handwheel. The surface of both sides or the whole surface of the shutter is covered by the seal element that is made of corrosion resistant, oil pollution resistant and high pressure resistant rubber material, therefore, the sealing area of the joint surface of the shutter and the valve body is greatly increased, thereby effectively avoiding the defects of small sealing area of the current flat gate valve and poor sealing performance.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind ofly not stopping under the situation that pipeline internal medium carries employed a kind of soft seal flap type when lateral is installed.
Background technique
ZL98228587.6 discloses a kind of plate valve, and this valve comprises valve body, flashboard, valve gap and handwheel, and its key is: in the connecting part of valve body and flashboard/in the connecting part of valve gap and valve rod seal ring is housed.This plate valve is imperfect, at first, because flashboard is made with metallic material, behind the barrier gate, the upper surface of flashboard and body cavity wall forms outside the very little sealing surface under the effect of seal ring, and lower surface seals in the mode of hard contact, the flatness that adds surface of contact is not good enough, the effect of fed sheet of a media self pressure, be difficult to obtain carry in the desirable sealing effect, particularly pipeline be gas the time, cause the gas escape easily, thereby can't realize band pressure branch operation; Secondly, owing to there is not sewage draining exit, the dirt that is produced in operation process inconvenience is discharged; The 3rd, because valve rod is exposed outside,,, get final product switch valve as long as a spanner is arranged even without handwheel, therefore, the medium of being carried in the pipeline has stolen cruel.
Summary of the invention
No matter the purpose of this utility model is on the gas pipeline or the pipeline of conveying liquid if being to provide a kind of, under the situation that does not stop the interior media conveying, finish lateral and install, sealing effect is good, and the medium of being carried in the pipeline does not have stolen cruel soft seal flap type.
The purpose of this utility model can reach by following technical measures: promptly: this soft seal flap type, comprise valve body, flashboard, valve rod, valve gap and handwheel, the sealing plain cushion is housed between valve gap and the valve body, valve gap links by packing ring and bolt and valve body, it is characterized in that: be coated with Sealing at flashboard two ends side face or whole peripheral surface; Axle sleeve, seal ring, O RunddichtringO, spacer ring and snap ring are equipped with in the inboard connecting part with valve rod of valve gap; The valve body bottom is provided with sewage draining exit and plug.
Described axle sleeve covers the connecting part of valve rod and handwheel;
The connecting part of described valve rod and handwheel is square or hexagonal shaped or flat-shaped;
The utility model compared with prior art, because flashboard two ends side face or whole peripheral surface are coated with Sealing, the sealing part by anticorrosive, oil resistant is dirty, the rubber material of anti-high pressure is made, flashboard is improved greatly with sealing area on the side face that valve body combines, thereby avoided effectively that existing plate valve sealing surface is little, the deficiency of sealing effect difference; Owing to " O " RunddichtringO is housed between valve gap and valve rod, nut and valve rod, can avoids fed sheet of a media effectively from valve gap position seepage; Because the valve bottom is provided with sewage draining exit and plug, can discharge, dredge the silt and the foreign material of body cavity at any time; Because axle sleeve covers the connecting part of valve rod and handwheel, when must not switch shape valve, as long as take off handwheel, just other people random switch valve, thus the stolen cruel of the interior institute of pipeline fed sheet of a media can effectively be avoided; Because the upper and lower end face flange of valve body is equipped with stud bolt, reduced the height of common gate valve, volume is reduced at double, thereby simplify the structure, reduced manufacture cost, widened application area, be particularly suitable on the pipeline of carrying liquid or gas, lateral being installed.
Description of drawings
Fig. 1 is the utility model overall construction drawing.
Embodiment
Below with reference to accompanying drawing concrete structure of the present utility model and working condition are further described.
A kind of soft seal flap type of the utility model, comprise valve body 1, flashboard 5, valve rod 6, valve gap 8 and handwheel, sealing plain cushion 7 is housed between valve gap 8 and the valve body 1, valve gap 8 links with valve body 1 by packing ring 10 and bolt 9, it is characterized in that: be coated with Sealing 4 at flashboard 5 two ends side faces, in the present embodiment, the sealing part is made by polytetrafluoroethylmaterial material, certainly do not repel coating Sealing 4 on flashboard 5 whole peripheral surface, the Sealing of this moment is made with Nitrile Rubber; Axle sleeve 14, seal ring 15, " O " RunddichtringO 13,16, spacer ring 12 and snap ring 11 are equipped with in valve gap 8 inboard connecting parts with valve rod 6; Valve body 1 bottom is provided with sewage draining exit and plug 2; Axle sleeve 14 covers the connecting part of valve rod 6 with handwheel 18.At valve body 1 upper and lower end face flange stud bolt 3,17 is housed.
According to the above-mentioned soft seal flap type that assembles, shake handwheel and make the valve rod rotation, thereby drive ram movement, realize the switching of gate valve.At the upper and lower end face of valve body stud bolt is housed, the stud bolt by the upper-end surface connects with driling machine, links by the stud bolt of lower end surface and the pipe clamp on the pipeline; Be provided with sewage draining exit and plug in valve body lower portion, start gate valve, after driling machine boring, back out plug, after pollutant exhaust hole is discharged valve body inscribe bits, tighten plug, closing gate valve, unload driling machine, connect lateral, press boring that lateral is installed thereby realize being with by stud bolt.
